[merged small][merged small][ocr errors][merged small][merged small][merged small][merged small]

To SAMUEL LAwson, of Leeds, in the county of York,

and John Lawson, of the same place, engineers and co-partners, for certain improvements in machinery for spinning, doubling, and twisting flax, wool, silk, cotton, and other fibrous substances,-being a communication. - [Sealed 2nd January, 1840.]

for certain 'wisting Leing a co

These improvements in spinning, &c., apply to that class or description of machinery called the throstle-frame, and are intended to effect economy of space in the machinery.

By this improved arrangement of parts, two sets of rovings, yarns, or threads, are spun, twisted, or doubled, from one set of drawing and top-rollers, each length of the rovings in spinning, or each pair or more of yarns or threads in doubling, being conducted to separate spindles and flyers, from the nip or points of contact of the lower row of the drawing-rollers.

The spindles and flyers are placed in two rows, at equal distances from a perpendicular line, drawn from the nip or point of contact of the lower rollers, in such a manner that the yarns or threads shall be conducted to the flyers at equal angles, and subjected to equal tension.

VOL. XXI.

In Plate Iy., fig. 1, is a side elevation of one of these improved spinning-frames, (having only twenty-four spindles,) as adapted for spinning flax, part of the guide-plates, with the apron, being removed, the better to shew the spindles and flyers in each row. Fig. 2, is a partial transverse section of the same; and fig. 3, is a section, to shew more clearly the line or direction in which the rovings or yarns are passed from the bobbins or spools between the sets of drawing-rollers to the flyers and spindles, and the situation of the same on each side of the perpendicular line a, b, shewn dotted in this figure.

a, a, is the frame-work and standard of the machine ; b, b, is the first or main driving-shaft, receiving its motion by a band passing from the steam-engine or other first mover, to the fast and loose pullies or riggers on its end ; C, c, are the rows of spindles, passing through the fixed plate or cross-bar d, their lower ends resting in cup-bearings on the other bar or plate e, in the usual manner; f, is the copping-rail or lifter, supporting the bobbins g, g; and h, h, are the flyers, attached to the spindles, as in common.

The copping or lifting motion of the bar f, is effected in this machine by the heart wheel or excentric cam i, acting upon one end of a lever, the other being attached to the legs or vertical bars k, k, which support the copping-rail; or the lifting motion may be effected in any other convenient manner. l, l, are the bobbins or spools, containing the rovings, threads, or yarns, and are placed in any convenient situation, turning loosely upon pins or wires; and m*, and m, are the two ordinary sets of rollers. These pairs or sets of rollers are constructed after the usual manner, and are actuated by the train of toothed wheels and pinions, leading from the main shaft b, to the axle n, of the lower set of drawing-rollers m, as shewn in the drawings. 0, 0, is the trouglı, containing the water for wetting the royings or yarns, when spinning or doubling flax, hemp, or such like fibrous materials. This trough is placed at or near the centre or middle part of the machine. p, p, are the guide-plates, for conducting and
